Caps Lock alarm

[don_AC64]

I have written this macro, that starts whenever I press the CapsLock key:

int wasoff=CapsLock(0)
if(wasoff)
CapsLock 0
shutdown -2
else CapsLock 1
mac "Beep"


And here is the function "Beep", that is called by the aforesaid macro:

start
bee "C:\Windows\Media\Windows Ding.wav"
wait 1
bee "C:\Windows\Media\Windows Ding.wav"
wait 1
goto start

So, whenever CapsLock is on, a repeating sound alerts me, similar to the sound that is activated in cars by the turn signal.
But I see that my macro is really coarse. Is there a simpler way to obtain the same result?
